IGN'ACY EDMUND PROMINSKI, OF BROOKLYN, NEW YORK.

RAILROAD-SWITCH.

Application filed August 1, 1916.

T 0 all whom it may concern:

Be it known that I, IGNAGY EDMUND PRO- )IINSKI, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a new and Improved Railroad-Switch, of which the following is a full, clear, and exact descriptlon.

My invention has for its object to provide a railroad switch simple in construction, which may be operated by the motorman from the car platform, without the necessity of stopping the car at a certam point.

Additional objects of the invention wlll appear in the following specification, in which the preferred form of the invention is described.

In the drawings, similar reference characters denote similar parts in all the views, in which- Figure 1 is a plan view illustrating my invention;

Fig. 2 is an enlarged plan view with parts broken away to illustrate the construction,

Fig. 3 is a side elevation of Fig. 2, showing the operating rod in position, and

Fig. i is an enlarged transverse sectional view of Fig. 1.

By referring to the drawings, it will be seen that a main rail is shown at 5, and a switch is shown at 6. A switch rail 7 is provided, which is pivoted at 8 in a manner readily understood.

The switch rail 7 is connected by a slotted link 9 with a rack 10, the link 9 being articulated at 11 to the switch rail 7, and the link 9 being articulated at 12 to the operating rack 10. In a slot 13 with which the link 9 is provided, there is disposed a stationary pin 1 which serves to direct the movement of the link 9 when it is operated by the operating rack bar 10.

The operating rack bar 10 is disposed horizontally on guides 15, there being a slot 16 in the rail 5, exposing the upwardly disposed rack teeth 17 on the rack bar 10. It will, of course, be understood that when Specification of Letters Patent.

Patented July 31 1917.

Serial No. 112,537.

the rack bar 10 is moved in one direction, it will serve to move the switch rail 7 to one position; while, by moving the rack bar 10 in the other direction, the switch rail 7 will be moved to its other position. As a means of moving the rack bar 10, I provide a rod 18 having teeth 19 at its lower end, it being possible to insert the teeth 19 of the rod 18 in mesh with the rack teeth 17 at any point, so that to operate the switch it will not be necessary for the motorman to stop exactly at a predetermined point, it being suflicient if the motorman stops near enough to the slot 16 to permit of the insertion of the operating rod 18.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a railroad switch, two converging rails, a pivoted rail for cooperating therewith, a horizontal rack bar disposed substantially parallel with one of the rails and with its teeth exposed, and means by which the rack bar is adapted to operate the switch.

2. In a railroad switch, two converging rails, a pivoted switch rail for cooperating therewith, a horizontal guideway under one of the converging rails, a rack bar disposed in the guideway, the last mentioned converging rail having a slot exposing the rack teeth of the bar, a slotted link articulated to the switch rail and to the rack bar, and a fixed pin disposed in the slot.

3. In a railroad switch, two converging rails, a pivoted switch rail for cooperating therewith, a horizontal guideway under one of the converging rails, a rack bar disposed in the guideway, the last mentioned converging rail having a slot exposing the rack teeth of the bar, a slotted link articulated to the switch rail and to the rack bar, a fixed pin disposed in the slot, and a rod having teeth at one end which may be disposed in mesh with the rack teeth for the purpose specified,

IGNAGY EDMUND PROMINSKI.
